+ \\(\frac{1}{2}\\) (purple rectangle)
\\(\frac{1}{8}\\) (green square)

Explanation:

Step1: Find a common denominator

The denominators are 2 and 8. The least common denominator is 8. Rewrite $\frac{1}{2}$ with denominator 8: $\frac{1}{2} = \frac{1\times4}{2\times4} = \frac{4}{8}$.

Step2: Add the fractions

Now add $\frac{4}{8}$ and $\frac{1}{8}$: $\frac{4}{8} + \frac{1}{8} = \frac{4 + 1}{8} = \frac{5}{8}$.

Answer:

$\frac{5}{8}$
